Has any one ever placed a larger tire in the spare tire/wheel storage under the bed of their truck? I assume they have some clearance under there? I was wondering if anyone has increased their oem tire size and added a larger spare? What size will fit? I myself am going to a LT295/55R20 E123/120Q 32.91 h x 12.52 W, provided my other posting about tire size doesn't convince me that I should consider a different tire/wheel configuration. This is for a short bed.
